Answer:
1 : 2
Step-by-step explanation:
Express the ratio as the number of oranges in each box, that is
box A : box B
= 18 : 36
Simplify the ratio by dividing both parts by 18, thus
ratio = 1 : 2 ← in simplest form
Use the law of cosines:
c² = 8² + 11² - 2•8•11 cos(37°)
c² ≈ 44.4402
c ≈ 6.66634
Answer:

Step-by-step explanation:
Solving for the variable
, given that :

We can first start start by subtracting
from both sides of the equation:

Now, we can divide both sides of the equation by the coefficient of
, which would be
:

Applying the fraction rule
:

Then, apply the fraction rule

log6 [x. (2x-7)]=log6 (6^2)
x. (2x-7)=36
2x^2-14x-36=0
2x +4
x -9
(2x+4)(x-9)=0
x= -2
x=9
